Weighted Additive Fuzzy Goal Programming Approach to Aggregate Production Planning

By Mohammed. Mekidiche Mostefa Belmokaddem Zakaria Djemmaa

DOI:, Pub. Date: 8 Mar. 2013

This study presents a new formulation of Weighted Additive fuzzy goal programming model developed by Yaghoobi and Tamiz [21]. and Yaghoobi et al [22] for aggregate production planning (WAFGP-APP), The proposed formulation attempts to minimize total production and work force costs, carrying inventory costs and rates of changes in Work force. A real-world industrial case study demonstrates applicability of proposed model to practical APP decision problems. LINGO computer package has been used to solve final crisp linear programming problem package and getting optimal production plan.
